Abstract: In August 2019, Brazil experienced the country’s greatest environmental disaster involving an oil spill appearing on the beaches. After 3 years, high volumes of tar balls appeared, raising questions regarding their possible relationship with the oil spill of 2019. Herein, an organic geochemistry investigation was performed using gas chromatography–mass spectrometry (GC–MS) and electrospray ionization coupled with Fourier transform mass spectrometry (ESI FT–MS), with the aim of characterizing the chemical compo… Show more

“…However, they are quite distinct from the GC profiles of the previous samples (Figure a). In particular, while the 2022.2 samples are bimodal in shape, with a low UCM (Figure S1e,f), , the n -alkanes of the 2022.1 samples are depleted significantly, with a very high UCM (Figure S1g,h), and the 2019 samples are unimodal, with a high UCM (Figure S1i,j). These findings were the initial evidence that the different sets of samples have distinct sources and that the 2023 oil spill represents a novel event off the Brazilian coast.…”

“…The 2023 samples have some physical similarities with the previous beached oily materials in 2019, 2022.1, and 2022.2, presenting a dark color, strong odor, and tar characteristics (Figure ). However, while the spilled oil in 2019 was a viscous liquid, , the 2022.1 spilled oil was small fragments and viscous liquid oils, , and the 2022.2 spill consisted of small to thick tarballs. , …”
